Steam-Water Separator Reheaters for Nuclear Power Auxiliary System

Project Overview

This project involved the fabrication and supply of 2 steam-water separator reheaters, engineered for the secondary circuit of a nuclear power plant. The equipment was delivered to Harbin Turbine Auxiliary Engineering Co., Ltd., a key contractor supporting turbine island systems in China’s large-scale nuclear energy sector.

The reheaters are designed to separate condensate from saturated steam and raise the temperature of the remaining steam for optimized turbine performance. Positioned between low- and high-pressure turbine stages, this system ensures reduced turbine moisture content, improved thermal efficiency, and extended blade service life.

Equipment Name :

Steam-Water Separator Reheater

Industry :

Nuclear Power – Steam System Equipment

Quantity :

2 Units

Client :

Harbin Turbine Auxiliary Engineering Co., Ltd. (China)

Technical Highlights:

  • Vertical shell-and-tube or pressure vessel-integrated reheater design
  • High-temperature alloy steels or stainless steel construction (e.g., SA213/TP347, SA336, pending specification)
  • Internal baffling, moisture separators, and steam coils tailored to nuclear-grade performance
  • Compliance with GB150, RCC-M, and ASME standards
  • 100% NDT, hydrotesting, and nuclear-grade material traceability
  • Delivered with full QA/QC documentation, weld maps, and quality records

Application Value:

  • Enhances thermal efficiency of the steam turbine cycle
  • Reduces steam moisture and erosion on turbine blades
  • Ensures long-term, stable operation in high-pressure, high-temperature nuclear environments
  • Critical to the safety and output stability of pressurized water reactor (PWR) systems

This project reflects our precision in manufacturing nuclear-grade thermal systems that meet the most stringent requirements of the power generation sector. As the nuclear industry evolves toward safer, more efficient, and larger-scale deployment, we remain a reliable supplier of customized steam-handling and auxiliary pressure equipment.
